All driveways and parking facilities shall be constructed in accordance with standards established by the Village Engineer and the following:
(A) Grading and Pavement. Parking facilities and access driveways shall be so graded and drained so as to dispose of all surface water and drainage so that such surface water and drainage shall not be allowed to flow onto adjacent properties including the right-of-way or remain standing in said driveways or parking facilities.
(1) All parking facilities and driveways improved or constructed shall be shall be asphalt, concrete or masonry type material. Stone or gravel is not considered a masonry type material. Alternative paving materials, such as porous/ permeable pavement, Grasscrete (or other pervious paving system) may be considered by the Village Engineer and the Planning Commission during development plan review.
(2) An adequate storm drainage system shall be provided for all parking lots in excess of eight thousand (8,000) square feet. For the purpose of square footage computation, all parking areas, access lines and truck loading areas on the same lot shall be considered as a contiguous total square footage.
(3) The design of a storm water drainage system shall be prepared by using the rational method and shall be based on a minimum five (5) year frequency. Rainfall intensity, runoff coefficients and concentration time used in computing flows and structure sizes shall be in accordance with the tables, charts, and data in the Village Storm Water Management Plan and shall be subject to approval by the Village Engineer and conform to all applicable county regulations. All areas that contribute storm water to the proposed storm drainage system shall be considered on the determination of the sizes of pipe, structures, and channels.
(4) Drainage plans shall be accompanied by two (2) copies of the design computations. Hydraulic gradient checks for less frequent storms may also be required by the Village Engineer were deemed appropriate.
(5) Culvert sizes shall be based on a minimum ten (10) year frequency rainfall, or other less frequency storms or greater number of years, or other more stringent methodology as required by the Village Engineer where deemed appropriate.
(6) Detention ponds or basins shall be provided where necessary to control the volume and velocity of storm water leaving the site. Detention ponds and basins shall be designed in accordance with any master watershed drainage plans. Where such plans do not exist, facilities shall be based on criteria established by the Village Engineer and approved by the applicable County Soil and Water Department.
(B) Marking. Any off-street parking facility for five (5) or more off-street parking spaces shall indicate the location of each parking space, the location of spaces for persons with disabilities, and the location and direction or movement along the aisles and access drives providing access thereto by painting upon the surface, by raised directional signs, or by markers or other similar measures placed in the surface.
(C) Maintenance. All parking facilities shall be maintained in a manner to keep it as free as practicable from rubbish, paper and other loose particles, and snow and ice shall be promptly removed. All signs, markers or any other methods used to indicate direction of traffic movement and location of off-street parking spaces shall be maintained in a neat and legible condition. Any walls, trees and shrubbery, as well as surfacing of the parking lot, shall be maintained in good condition throughout its use for parking purposes. It shall be the responsibility of the property owner to maintain and repair parking lots as may be necessary, in the opinion of the Village, so as to provide a surface free of excess dust that is in good condition, properly drained, and free of obstructions and nuisances in accordance with the requirements of this Article.
